PLOW ATTACHIVI ENT- SPECIFICATION forming part of Letters PatentN0.,7'70,412, dated September 20, 1904.

Application filed March 11, 1904.

To (LZZ whom, it may concern:

Be it known that 1, WILLIAM N. ALLEN, a citizen of the United States,residing at Ironton, in the county of Lawrence and State of Ohio, haveinvented a new and useful Plow Attachment, of which the following is aspecification.

This invention relates to plow attachments; and it has for its object toprovide a device simple in construction and easily applied by means ofwhich plows of ordinary construction may be employed in gangs composedof any desired number of units.

The invention consists in the improved construction and arrangement ofparts, which will be hereinafter fully described, and particularlypointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being understood, however, thatI do not necessarily limit myself to the precise structural detailstherein exhibited, but reserve the right to any changes, alterations,and modifications which may fairly fall within the scope of theinvention and which may be resorted to without departing from the spiritof the invention or sacrificing the utility of the same.

.Figure 1 is a perspective view of my improved plow attachment. Fig. 2is a bottom plan view of the same. Fig. 3 is a transverse verticalsectional view. Fig. 4 is a sectional view taken at right angles to Fig.3. Fig. 5 is a plan view showing a pair of plows spaced and connected bymy improved attachment.

Corresponding parts in the several figures are designated by likenumerals of reference.

My improved plow attachment comprises in its preferred form an upper anda lower plate, (designated, respectively, 1 and 2,) said plates beingprovided on proximate sides with alternate ribs 3 and recesses 4,adapted to interlock with each other and to secure the said platesagainst transverse movement with relat ion to each other. Each of theplates 1 and 2 is provided with a pair of transverse slots 5 for thereception of connecting members, which have been illustrated ascomprising bolts 6 and nuts 7 Washers 8 are inter- Serial No. 197,692.(No model.)

posed between the nuts and the proximate plate.

The lower plate 2 is provided at one edge with a downwardly-projectingflange 9, extending from its rear edge in a forward direction, but notentirely to the front edge of the plate. The front edge of the flange 9merges with a transversely-disposed flange 10, which depends from thetop plate 2. The flanges 9 and 10 are provided with perforations 11 forthe passage of bolts or other suitable fastening devices by means ofwhich the said flanges may be securely connected with the front end ofthe plow-beam 12, with which the plate 2 is thus securely connected,said plate extending, as will be seen, some distance in front of theplow-beam, to which it is attached.

The upper plate or member of the device is provided at the end which isdistant from the end of the plate 2, having the dependent flange 9, witha depending flange 14, having perforations, as 15, for the reception offastening members, by means of which it may be connected to the side ofa plow-beam 16 at a suitable distance in the rear of the front end ofsaid beam.

The operation of this invention will be readily understood from the.foreoging description, taken in connection with the drawings heretoannexed. The plates or connecting members 1 and 2 having been attachedto the respective plow-beams in the manner indicated, said plates areconnected by means of V the bolts 6, the plow-beams being spaced anysuitable distance apart by properly adjusting "the plates 1 and 2 withrelation to each other,

this being readily accomplished prior to the placing of the bolts orconnecting members by properly adjusting the interengaging ribs andrecesses of the respective plate members.

.It is obvious then that by simply tightening the bolts the plow-beamsto which the plates have been attached will be connected with a degree-of rigidity that absolutely precludes the possibility of their beingdisplaced or their relative positions distorted when the device isin'operation as a gang-plow. The importance of such rigid connection isso well known as not to require to be enlarged upon, and this rigidityis established not only by the interlocking of the plate members 1 and 2with each other, but also by the securing means with which said platemembers may be connected with the respective plow-beams. It will be seenespecially that the lower plate member 1, which isattached to the noseof the rear plow-beam, will be connected therewith by fastening meansextending through the flanges 9 and 10, which are at right angles toeach other, thereby forming a connection which will prevent theplow-beam from swaying, and it will insure the plow being kept in thedirect line of the draft. It will also be seen that the draft upon thesecond and upon each succeeding plow will be applied directly to thefront end of the beam, the advantage of which in keeping the plow in thedesired line of action is obvious.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is I l. A device for connectingplow units to constitute a gang, consisting of a member having adependent flange adapted to be attached to the side of a plow-beam, amember having dependent flanges at right angles to each other adaptedfor attachment to the nose of a plowbeam, and means for operativelyconnecting said members.

2. A device for connecting plow units to form a gang, the sameconsisting of a member having a dependent flange adapted to be connectedwith the side of a plow-beam, a

member having depending flanges at approximately right angles to eachother, and means for adjustably connecting said members to space theplow-beams connected therewith any desired distance apart.

3. A device for connecting plow units to constitute a gang, the sameconsisting of a member having a dependent flange adapted to be connectedwith the side of a plow-beam, a member having depending flanges atapproximately right angles to each other adapted to be connected withthe nose of a plow-beam, and a connecting means for said members, thelatter being provided with alining slots for the passage of saidconnecting means, and said members being provided in their proximatefaces with longitudinally-disposed interengaging alternate ribs andgrooves.

4. A device for connecting plow units to constitute a gang, the samecomprising a memberhaving a downwardly-extending flange to be connectedwith the side of a plow-beam, a member having downwardly extendingflanges approximately at right angles to each other adapted to beconnected with thenose of a plow-beam, interengaging locking means uponthe approximate faces of said members, and means for connecting thelatter in adjusted position.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

WILLIAM N. ALLEN.
